The ECM-B10 lets you record pro-quality audio with your compatible Sony camera. It uses advanced beamforming technology to optimize its three switchable polar patterns, including its super-directional mode that helps you zero in on a source in front of you. Your camera's Multi Interface Shoe provides power and passes audio signals directly to your camera. For Sony cameras that have a built-in digital audio interface — like the a7R IV — the audio signal transfers directly to the camera in digital form, so you can get pristine sound with near-zero degradation. You can also switch it to analog mode to work with a wider range of cameras. Virtually noise-free recording This mic's physical design suppresses low-frequency noise from shock and vibration. A switchable filter also cuts out noise or super-low frequencies that can muddy your recording. Plus, it comes with a furry windscreen for cutting noise when you're recording outside. It mounts to your camera's shoe, which eliminates noise transmitted through cables or connectors. That helps you get great sound at the recording stage and keeps your post-processing to a minimum.
